Eyes of Generosity

I found that artistically this variation of Rarities face is absolutely amazing but so overdone, never less it's still beautiful.

The appearance of the pony: With the way your art style is It definitely not hard for the people who don't know the characters of the show to see exactly which character you were making an art piece of. She also looks close to what some might say more realistic then, then her actual looks in the show.

The little details: From the way, the outline is with her coat, to her eye detail (plus the sparkle) to the hair strands in her mane. All of what I mentioned make her look absolutely beautiful to look at instead of her being a cut and copy from someone else.
